Revision 3
Safety edge function
The principal functions of the three safety edge inputs are:
• SE.C1 for closing movement
• SE.C2 for closing movement
• SE.O1 for opening movement
• SE.O2 for opening movement
Connection and function, C104
In this channel a choice is made of whether a safety edge is to act on movement for one motor or on both motors.
In the case of EP104-1, all connected safety edges will act on a connected motor. In the case of EP104-2, it is possible to
choose between letting a connected safety edge act on movement for both motors, C104=1, or only one of the motors,
C104=2.
If C104-3 is chosen, the input SE.O2 will cause stopping in activation in both opening and closing. This function can be
used for example to protect a door installed in the door leaf.
Safety edge functions – general
These settings are the same for a safety edge for the closing movement and a safety edge for the opening movement.
• Reverse/stop
In these channels you select whether the gate/door is to reverse or stop when the safety edge is activated.
• C112, selection of reverse or stop for SE.C1
• C122, selection of reverse or stop for SE.C2
• C132, selection of reverse or stop for SE.O1
• C142, selection of reverse or stop for SE.O2
1 = Reverse
2 = Stop
Option 1, Reverse, the unit will move in the opposite direction after a delay specified in channel C493.
!
Option 2, Stop, stops the door without reversing. Must be used with care as the lack of the reverse function means
someone may become trapped.
• Reverse delay.
The delay between activated safety edge and when the change of direction begins may be set in channel C493.
Safety edge function in the closing movement
On delivery and after a factory reset, the EP105 is configured to reverse to the fully open position when the safety edge is
activated in the closing movement.
Safety edge function in the opening movement
On delivery and after a factory reset, the EP105 is configured to reverse when the safety edge is activated in the opening
movement.
Reverse does not take place to the closed position, but during the time specified in C494.
Low speed after safety edge activation (Only when using a frequency inverter)
Using this setting the gate can be allowed to close slowly if it has reversed due to a safety edge. This is to prevent it closing
on any remaining obstacle with full force. Set C105 either to 0 to deactivate the function or 1 to activate it, bearing in mind
that this is only possible when using a frequency converter.
Performance testing safety edges
Check that the automatic control unit reacts as intended as configured above when the safety edge is activated.
Check that the LED indicates activated safety edges SE.C1, SE.O1, SE.C2 and SE.O2.with a constant light. Also check that
the safety edges flash when they are no longer activated.
F
Use L001 and L002 to disable one or the other motor by specifying 0 in one of these channels.
